Flexuline

Flexuline Barbell Squat - Whether it's the front squat or the back squat, when it comes to overall mass development, the squat is virtually unsurpassed. Since you recruit so many different muscles throughout the movement, it is quite literally the king for overall mass gain. There is much controversy on whether you must squat parallel or even lower. I have trained with Olympic weightlifters who squat all the way to the ground and they have never as much as hinted at any knee problems. So there you go.
